- Аннотация: Polycrystalline samples of novel compounds Ce0.67Pd2Al5, Ce1.33Pd3Al8, and Ce1.74Pd5.29Al11.71 were prepared by arc-melting. The crystal structure of the latter compound was determined from the single-crystal X-ray diffraction data to be a disordered variant of the hexagonal Th2Ni17 type [P63/mmc, a = 9.1961(5) Å, c = 8.8861(5) Å]. The crystal structures of the other aluminides were examined by powder X-ray diffraction and found to be isotypic with Sc0.67Fe2Si5 [P63/mmc, a = 4.3385(5) Å, c = 16.5255(15) Å] and Gd1.33Pt3Al8 [Rm, a = 4.37960(10) Å, c = 39.1683(9) Å], respectively. Based on the thermodynamic and electrical resistivity data measured down to 0.4 K in external magnetic fields up to 9 T, the new materials were characterized as metallic Curie-Weiss paramagnets due to fairly stable trivalent Ce ions. In Ce1.33Pd3Al8, an antiferromagnetic ordering was established below TN = 2.3 K, while no long-range magnetic order was found in the other compounds. All three phases exhibit electrical conductivity that is governed by the interplay of Kondo and crystalline electric field interactions, and significantly affected by structural disorder inherent to their crystal lattices.
